near to Dunfanaghy, Port and Muntermellan, Donegal, Ireland

Fire hydrant cover located on a road south-west of the centre of Dunfanaghy (Old Cottage Road on the Google maps, but this may be incorrect). The cover was cast by Tonge and Taggart of Dublin - their works were based at the South Dublin Foundry in Windmill Lane but (I think) it closed in the mid 1980s. Further information welcomed.
